To all whom #may concern:

Be it known that I, JOHN. citizen of the United States, residing .at Buffalo, in the county of Erie and State of New York, have invented-a new and useful Improvement in -Non-Refillable Bottles,

of which the following is a specification., e

This invention relates to improvements in nonrefillable bottles,and has for its object to provide a simple, practical and inexpensive stopper for a bottle which will successfully operateto prevent the refilling o f the,

same. Y

. In theraccompanying drawings: rFigure` l g5 is a fragmentary sectional elevation of a bottle providedwith a stopper embodying the invention.` Fig'. 2 is a similar View with the bottle inverted. Fig. 3 is a similar viewy of the bottle in its tilted or pouring posi` 2O tion.

Like reference characters refer to like parts in the several figures.

A represents a bottle which is' provided with a neck a having inwardly tapering walls as is usual in bottles-of V.this type. Vtithin the neck a is arranged a r.conical shaped stopper B which is adapted to fit snugly therein and may be secured in place in any suitable or desirable manner.' In the construction shown, the outer face' of the stopper is provided at its inner end with a reduced annular portion b in which a packing ring b of cork or other suitable material is cemented or otherwise suitably secured and the neck of the bottle is pro-l vided with inwardly projecting ribs b2. When the stopper is inserted in the neck of the bottle the packing ring Z1 is adapted to firmly grip the annular ribs 102 on the e0 inner face of the neck and thus firmly secure the stopper in position and prevent its removal.

In the stopper B is arranged a longitudinally extending opening or passage C which e5 is provided intermediate of its ends with an enlarged valve chamber' c and at its inner end with a contracted opening or throat c. In the valve chamber c is located a valve D, preferably of the gravity ball type, and the chamber e at its opposite ends has valve seats d and d for this valve, so that when the bottle is in either its upright or inverted position, this ball valve will rest on its re-v spective valve seat and thus close the passage C. When, however, the bottle is turned to its inclined or pouring position as shown in Fig.v 3,'theball valve D will rest againsty i the lower side of the chamber c, as shown, and thus `will not-interferefwith the pouring of theliquid from the bottle. In t-he contracted opening or throat 0 at the inner end ofthestopper is arranged a second valve E, preferably of dumb-bell shape, having a head e `which lies Within thepassage C, a neck e extending through the contracted opening c and an enlarged body portion 2 lying without the inner end of the stopper. The head e is adapted to firmly seat on the sidesl of the stopper 'forming the contracted opening or throat c so as to closethis opening whenthe bottle is in its upright posi tion vand thus prevent the passage ofI liquid into the bottle.' V'Vhen the/bottle is turned to its' inclined Vor pouring position as shown in Fig. 3,the weightof the body portion e? of the valve E willcause this'valveto shift its` position so'as to' allow the liquid to pass through lthe opening of. flow of liquid .throughthis opening, the body portion 62, maybe provided with longitudinal groovesbr channels e3 which are of sufficient length toiextend through the opening c when the bottle is in its pouring position and thus permit a greater quantity of liquid to pass thr'ou h thesame To prevent access tothe va ve D, a perforated plate G is provided which extends lacross the passage C and has its outer edge secured in the walls of the stopper.

The stopper is simple in construction, can be cheaply manufactured, and can be readily secured in place in the bottle, and the bottle in which it is used can be as economically manufactured as bottles of this general type which arg now manufactured. The employ ment of the two valves makes itgpractically impossible to refill the bottle. The outer valve also serves to protect the inner valve To vfacilitate the i from being tampered with so that even if I the outer valve is forcedl open, access can not be had to theinner valve for moving it from its seat. In manufacture the stopper is preferably formed .of two longitudinal half sections. This permits thevalves and the plate G to be readily inserted in place between the sections, and the sections can then be secured together in any suitablemanner. In case thebottle should become broken or unfit for use, the' stopper can he forced out ofthe neck of the bottle from the inside and can then be used over agai in another bottle. Alfter the stopper has been inserted in the neck of the bottle, the cork packing rino' on the outer side of the stopper will swl so that it will firmly engage the ribson the inner side of the neck of the bottle and hold the stopper securely in place therein.

I claim as my invention: l

l. In a non-rellable bottle, the combination with the neck of the bottle, of a stopper therefor having a discharge passage- Way extending through the same, a valve arranged in said passage-Way intermediate of its ends, opposed valve seats for said valve which are arranged-to be engaged by said valve for closing said passage-way When the bottle is in its upright and inverted positions respectively, a second valve arranged in the inner end of said stopperand adapted to close said passage-Way when the bottle is in its upright position, said second valve having a Weighted portion which extends beyond the innerend of said stopper and is'adapted to cause said valve to open and close as the bottle is moved to and from its upright and inclined positions, and means for securing said stopper in the neck of the bottle, substantially as set forth.

2. In a non-reillable bottle,- the combination with the neck of the bottle, of a stopper therefor having a passage-Way which extends through the saine andis provided intermediate of its ends with a valve chamber havin@ opposed valve seats, and at its inner en with a contracted opening, a valve arranged in said valve chamber and adapted to engage saidi opposed valve seats for closing said passage-Way when the bottle is in its upright and inverted positions respectively, a second valve arranged in the inner end of said stopper for closing said contracted opening and having a Weighted portion which extends through said opening into the bottle,'and means for securing said stopper in the neck of the bottle, substantially as set forth.

3. In a non-refillable bottle, the co1nbination with the neck of the bottle, of a stopper therefor having a discharge passage- Way extending through the saine, a valve arranged in said passage-Way intermediate of its ends, opposed valve seats for said valve which are arranged to be engaged by said valve for closing said passageway when the bottle is in its upright and inverted positions respectively, a valve seat arranged in said passage-way adjacent to the inner end of said stopper, a valve adapt; ed to engage said seat for closing said pas- Sage-Way, said valve having a Weighted portion Which'operates to hold said yvalve on said seat when the bottle is in its upright position and to move said valve from said seat when the bottle is in an inclined position, and means for securing said stopper in the neck of the bottle, substantially as set forth.
